TRANSMISSION MECHANISM FOR Application flled'July 1,

T 0 all whom it may concern.

Be it known that I, EMIL R. DRAVER, a citizen of the United States, residing at -Richmond, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Transmission Mechanism for Feeders Connected in a Gang; and I do hereby declare the following to be a full, clear, and exact description w ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to transmission mechanism for feeders connected in batteries and is in the nature of an improvement or refinement .of the construction dis- 0 in accordance with my invention;

Fig.2 is aview in side elevation illuse trating a somewhat modified construction of the transmission mechanism; I

Fig. 1 is a left side elevation of the power delement of thebattery shown in Fig. 1;

an Fig. 1" is a'left side elevation of one of the feeders shown inFig. 1'.

Describing first those features that are 9 common to all of theviews, the numeral 3 indicates the entire cash through which either grain orother. stoc is arranged to be fed under theaction of gravity, and preferably, by the action of a rotary paddle & wheel not herein shown, but such, for example, as that illustrated in my said rior application. Such paddle wheel wou d be secured to a shaft 4 rotatably mounted in the sides of each casing 3 and having at one projecting enda ratchet wheel 5 that is sub ect to reverselyacting dogs 6 carried by arms 7 pivoted on the shaft 4. The free ends of arms 7 are connected by links 8 to a FEEDERS CONNECTED IN A GANG.

crank head 9 mounted to slide on an oscillatory arm 10. The head 9 is adjustable toward and from the pivot of the said lever -10 by means of an adjusting screw 11 swiveled to a projection of said arms 10 and engaging a nut 12 that is located between lugs 13 of the head 9. i The head 9 is adapt- 5 ed to be rigidly secured to the arms 10 in any desired adjustment by additional securing means, such as a set screw 14.

The oscillatory arm 10 is pivoted to a stud 15 on a bracket 16 formed as a part of, 5 or rigidly secured to one of the sides of the casing 3. The construction which will now be further and immediately described, is that illustrated in Figs. 1, 1 and 1 The numeral 18 indicates laterally spaced side frames which, as shown, are tied to-' gether by rods 19 constituting the framework of a power device that is common to all of the several laterally spaced feeders. The numeral 20 indicates a driving pulley normally loose on a counter shaft 21 that is j ournaled in the side frames 18. This ulley is adapted to be connected to and soonnected from the shaft 21 by means of a suitable lever-actuated clutch 22 of any suitable. construction, but preferably of substantially the arrangement disclosed in may said prior application.

At one end, towit, as shown, at its left hand end, shaft 21 is provided with a short crank 23 which, by means of a link 24, is connected to an oscillatory arm 25. arm 25 is-secured to one end of a shaft 26 journaled in suitable hearings on the side frames 18 of the power device. Said arm is provided with a flanged face 25 upon which a bifurcated crank head '27 is mounted to slide. This head is adapted to be set in different adjustments varying the distance from' shaft 26, by an adjusting screw 28 swiveled to a pro ection of the arm 25 and engageable with a nut 29 that works between spaced lugs 27 of the head 27 The numeral 30 indicates a long rock: shaft that is journaled in suitable bearings 18' on the side frames 18 and to suitable bearings 3 on the side of the several casings 23. At one end, towit, as shown in Fig. 1, at its left hand end, this common rock shaft 30 is provided with an arm 31 which,-'-as 1 shown, is bifurcated and pivotally connected to a link 32, the other end of which link is pivotally connected to the ad'ustable block arm 10.

27 and is adjustable therewit The common rock shaft 30, adjacent to one side of its casin 3 is provided with an upwardly projected arm 33 that has a laterally projecting stud 34. For each arm 33 there is a connectin link or rod 34 provided at its free end with a notch 35 for detachable engagement with the co-operating stud 34 The other end of each such connecting link is pivotally connected to the co-operating oscillatory arm 10 previously described. At its intermediate portion, the said links 34 are made loop form so as to aflord large clearance around the projecting portion of the co-operating shaft .4.

In the construction illustrated in Fig. 2, the primary power device and the common transmission shaft are of modified arrangement and comprise as follows:

The numeral 36 indicates a pulley secured to a shaft 37 journaled in a suitable overhead support 38 and provided at one end with a face friction wheel 39 that co-operates with a peripheral friction wheel 40 secured to a suitably supported counter shaft 41. Friction wheel 40 is movable on shaft 41, toward and from the axis of wheel 39 to produce a variable speed transmission of power. Shaft 41 is provided with a pulley 42. A belt 43runs over pulley 40 and over another pulley 44, which latter is secured to a shaft 45. This shaft 45, in this arrangement, constitutes the common power transmission element, but is a continuously rotating shaft rather than a rock shaft. When the several feeders are connected in a battery, shaft 45 will extend alon the several machines and will be journale in suitable bearings on the casings thereof. Adjacent to one side of each feeder, a common shaft 45 is provided with a spur pinion or gear 46 that meshes with agear 47 that is journaled to a stud 'on one side of the feeder casing and provided with a crank pin 47. The numeral 48 indicates a long link pivotally connected at one end to the free end of the co-operating arm 10 and provided at .its other end with a notch 49 for detachable engagement with the crank pin 47. In this arrangement, the gear 47 and its crank pin 49 a 0rd the crank for oscillating. the

-- ley 20, and hence,jthe crank shaft 21 will be driven at a constant speed; Through the connections described, the common rock shaft 30 will, of course, beoscillated when the saidvfilulley and crank shaft are'driven,

and it be given one complete backandw forth oscillation foreach complete rotation feeders. With the arms 33 given a predetermined angular oscillation, at a definite speed, the rotation of the rotary members of the respective feeders will depend on the adjustments of the crank heads 9 of the reis provided, first, means for simultaneously varying the speed or rate of feed movement of all of the feeders, and second,.means for further varyin the rate of feed movement of the several feeders, the one independently of the other, and all ofthis without changing the speed of the primary driving shaft ;or element. Moreover, any one of the feeders may be quickly thrown out of action or back into action without interrupting the oscillatory movements of the common rock shaft, simply by disengaging one of the connecting links 34 from its co-operating stud 34 of the respective arms 33. Of course, by means of a clutch 22, ulley 20 may be dis connected from crank s aft 21, thereb stopspective feeders. Hence, as is evident, there ping all of the several feeders and t e pr1- r I mary driving mechanism without interrupting the rotation of said pulley.

The above described adjustments and noted actions make it ossible, first to set several machines for di erent proportionate rates of feed and then, without changing this proportionate rate of speed, to simul-' taneously increase or decrease the rates of feeding actions of the several feeders, as occasion may require. Different kinds of work and different conditions of stock make the above noted various adjustments highly desirable,

In the construction illustrated in Fig. 2, adjustments of friction wheel 40 toward and from the axis of friction wheel 39 serve to simultaneously vary the-rate of feeding action of the several feeders without changing the proportionate relative rate of feed thereof; and by independent adjustments ofthe crank heads 9 onjthe arms 10, the relative 'ratesof feeding ers may be independently. varied.
